These low-level routines must be called by programs that
have to deal directly with the terminfo database to handle
certain terminal capabilities, such as programming function keys. For all
other functionality, curses routines are more suitable and their use
Initially, setupterm() should be called. Note that
setupterm() is automatically called by
initscr() and newterm().
This defines the set of terminal-dependent variables
[listed in terminfo]. The terminfo
variables lines anjd
columns are initialized by
setupterm() as follows: If
use_env(FALSE) has been called, values for
columns() specified in terminfo() are
used. Otherwise, if the
environment variables LINES and COLUMNS
exist, their values are used. If these environment variables do not exist
and the program is running in a window, the current window
size is used. Otherwise, if the environment variables do
not exist, the values for lines and
columns specified in
the terminfo database are used.
The header files curses.h and
term.h should be included
(in this order) to get the definitions for these strings,
numbers, and flags. Parameterized strings should be
passed through tparm() to instantiate them. All
strings [including the output of tparm()] should be
printed with tputs() or putp(). Call the
reset_shell_mode() to restore
the tty modes before exiting [see curs_kernel()].
Programs which use cursor addressing should output
enter_ca_mode() upon startup and should output
before exiting. Programs desiring shell escapes should call
reset_shell_mode() and output
exit_ca_mode before the shell
is called and should output enter_ca_mode and call
reset_prog_mode() after returning from the shell.
The setupterm() routine reads in the
terminfo database, initializing the
terminfo structures, but does not set up the
output virtualization structures used by curses. The
terminal type is the character string term; if
term is null,
the environment variable TERM is used. All output is to
file descriptor fildes which is initialized for output.
If errret is not null, then setupterm()
returns OK or ERR
and stores a status value in the integer pointed to by
errret. A status of 1 in errret is normal, 0
the terminal could not be found, and -1 means that the
terminfo database could not be found. If
errret is null,
setupterm() prints an error message upon finding an error
and exits. Thus, the simplest call is:
setupterm((char *)0, 1, (int *)0);
which uses all the defaults and sends the output to stdout.
The setterm() routine is being replaced by
setupterm(). The call:
setupterm(term, 1, (int *)0)
provides the same functionality as
setterm() routine is included here for BSD compatibility,
and is not recommended for new programs.
The set_curterm() routine sets the variable
cur_term to nterm, and makes all of the
terminfo boolean, numeric, and string variables use the
values from nterm. It returns
the old value of cur_term.
The del_curterm() routine frees the space pointed to by
oterm and makes it available for further use. If
oterm is the same as cur_term(), references
to any of the terminfo boolean, numeric, and string variables
thereafter may refer to invalid memory locations until another
setupterm() has been called.
The restartterm() routine is similar to
setupterm() and initscr(),
except that it is called after restoring memory
to a previous state (for example, when reloading a game
saved as a core image dump). It assumes that the windows
and the input and output options are the same as when memory was saved, but
the terminal type and baud rate may be
different. Accordingly, it saves various tty state bits,
does a setupterm(), and then restores the bits.
The tparm() routine instantiates the string
str with parameters pi. A pointer is returned
to the result of str with the parameters applied.
The tparam() routine is included for compatibility with the
GNU termcap implementation. It works like tparm() but you
specify a buffer and buffer size to be filled with the expanded string.
The tputs() routine applies padding information to the
string str and outputs it. The str must be a
terminfo string variable or the return value from tparm(),
or tgoto(). affcnt is the number of lines
affected, or 1 if
not applicable. putc() is a
putchar()-like routine to which the characters are passed,
one at a time.
The putp() routine calls
tputs(str, 1, putchar). Note that
the output of putp() always goes to stdout,
not to the fildes specified in setupterm().
The vidputs() routine displays the string on the terminal
in the video attribute mode attrs, which is any combination
of the attributes listed in curses. The characters
are passed to the putchar()-like routine
The vidattr() routine is like the
vidputs() routine, except
that it outputs through putchar().
The mvcur() routine provides low-level cursor motion. It
takes effect immediately (rather than at the next
The tigetflag(), tigetnum() and
tigetstr() routines return the
value of the capability corresponding to the terminfo
capname passed to them, such as xenl.
The tigetflag() routine returns the value -1 if
capname is not a boolean capability.
The tigetnum() routine returns the value -2 if
capname is not a numeric capability.
The tigetstr() routine returns the value
(char *)-1 if capname is not a string capability.
The capname for each capability is given in the table column
entitled capname code in the capabilities section of
- char *boolnames, *boolcodes, *boolfnames
- char *numnames, *numcodes, *numfnames
- char *strnames, *strcodes, *strfnames
These null-terminated arrays contain the capnames, the
termcap codes, and the full C names, for each of the
Routines that return an integer return ERR upon failure
and OK (SVr4 only specifies "an integer value other than
ERR") upon successful completion, unless otherwise noted
in the preceding routine descriptions.
Routines that return pointers always return NULL on
The setupterm() routine should be used in place of
It may be useful when you want to test for terminal capabilities without
committing to the allocation of storage
involved in initscr().
Note that vidattr() and vidputs() may
The function setterm() is not described in the XSI Curses
standard and must be considered non-portable. All other
functions are as described in the XSI curses standard.
In System V Release 4, set_curterm() has an
int() return type
and returns OK or ERR. We have chosen to implement
the XSI Curses semantics.
In System V Release 4, the third argument of tputs() has
the type int (*putc)(char).
The XSI Curses standard prototypes tparm() with a fixed
number of parameters, rather than a variable argument list.
